Title: Improvements in method of forming elements from molten material
IPC: C03B15/00
Filed: 1939-07-25
Abstract: 531,514. Glass manufacture. SIMONS, A. July 25, 1939, No. 21581. [Class 56] [Also in Groups XXII and V] A sheet A, Fig. 1 is produced from molten glass supplied to a bath B and regulated in height by an adjustable displacer 35 through which the glass is fed. Any solid particles in the bath are removed periodically through a tap hole 39, water cooled rolls 31 with grooves and vents in their peripheries connected to an exhauster at 63 cause a film of glass to form and cling to them, the film thickening as it rises from the bath. On approaching the line of centres the two films are pressed together and unite and the sheet is further drawn up and .finished by water cooled rolls 64. The vents in the rolls 31 are formed by grooves containing sinuous strips 55 that leave long narrow spaces 56 that exhaust air but will not pass glass. The strips are bevelled at their lower edges to form channels 51, Fig. 8, communicating with passages in the ends of the roller communicating with chambers 61 formed in hoods 60. In a modification a single roller is mounted above the level of the bath 71 Fig. 9, and the glass is drawn up by suction along one side of the roller to form a sheet that is finished by a water cooled roll 75 and passes from the vacuum chamber under a sealing member 78 to further rolls at 85. The glass level is controlled by a float 81 that controls a valve 80 in the exhauster pipe. A brush 82 removes any particles that may adhere to the roller. Various other modifications employing single and double rollers are illustrated by diagrams with various arrangments of the baths some of which are electrically heated. In a further modification two half round channels formed by correspondingly shaped rollers are pressed together to form a tube. Rollers with multigrooves can produce a number of rods or tubes simultaneously. In a further modification a sheet or strip D, Fig. 18 passes from a reel 121 between heating furnaces 123 with baths above and films of another glass picked up by the rollers 122 are united to the sheet D to form a compound sheet. In a further modification the two baths contain different glasses and a compound sheet is formed without the interposition of a solid insert.

Abstract: 1,221,335. Nitric acid, concentration by distillation. BADGER CO. Inc. 7 May, 1968 [22 May, 1967], No. 21641/68. Heading B1B. Concentrated nitric acid is obtained from dilute nitric acid solution (55 to 64% HNO 3 ) flowing through line 18 by adding, through line 20, concentrated acid to the dilute acid to form a mixture which is stronger than 68% HNO 3 , distilling the mixture at sub-atmospheric pressure in column 12 to obtain concentrated acid overhead, recycling a portion of the overhead condensate, through lines 22 and 20, to the dilute acid to be concentrated, refluxing another portion of the concentrated acid to the head of column 12, and withdrawing the required product through line 32. Column 12 is preferably operated at a reduced pressure in the range of 300 to 450 mm. Hg, maintained by a vacuum pump connected to line 36. The aqueous acid passing down column 12 collects on plate 16. Some of this acid is withdrawn through line 44 and boiled in heat-exchanger 46, the vapours being returned to column 12 through line 48. Another portion of the aqueous acid collected on plate 16 flows through line 42 to column 14, which is heated by reboiler 50 and is maintained at superatmospheric pressure, e.g. 1,200 to 1,800 mm. Hg. Water-vapour leaves the top of column 14 and flows through line 60 to heat-exchanger 46, from which part of the water-condensate is refluxed through line 66 to column 14 while the remainder is discharged from the system through line 62. Part of the concentrated acid which collects in the base of column 14 is passed through lines 70 and 74 to column 12.

Title: Amplification arrangements for time division multiplex systems
IPC: H01Q7/06
Filed: 1961-06-16
Abstract: 966,583. Automatic exchange systems. STANDARD TELEPHONES & CABLES Ltd. June 16, 1961 [July 21, 1960], No. 21838/61. Headings H4K and H4R. In a system in which connection between two subscribers LP, LP<SP>1</SP> is effected by resonant transfer between storage devices C 0 , C during one time position of a cycle and between storage devices C, C<SP>1</SP> 0  during a second time position a gate G 3  interconnecting the storage device C with a negative resistance - R is closed for at least a portion of the period between the time positions, thereby providing amplification to compensate for bosses in the transmission system and/or losses in the charge stored in device C. Connections may be effected over a single highway. The gate G 3  may be opened during a guard period between sampling pulses, e.g. the guard period immediately succeeding the resonant transfer period. In this case a single negative resistance - R may be used in common to all the condensers C. Alternatively, separate negative resistances may be used for each condenser C, the gate G 3  being opened for the whole of the intervals between the resonant transfer times. Thus if, using a multiplex cycle of 2n channels, it is possible to relate each channel on highways H 1 , uniquely with a corresponding channel on H 2  then it is convenient that the spacing shall be equivalent to n channels so that e.g. t 1  on H 1  corresponds to t n+   1  on H 2 , i.e. the pulses on H 2  are midway between those on H 1 . The gate G 3 , for the corresponding condenser C and negative resistance - R, may then be opened for equal periods, viz. that between t 1  and t n+1  for one direction of transmission and that between t n+1  and t n2+1  (#t 1 ) in the other direction. If the unique relationship cannot be established then arrangements may be made that the deviation from the mid-point relationship may not be too great. Thus a control circuit, Fig. 3, may be provided in which for a 10-channel system leads A 1  . . . 10 are energized in accordance with free channels on H 1  and leads B 1 ... 10  are energized in accordance with free channels on H 2 . Gates G16 are provided only for those channel combinations for which the midchannel relationship is not greatly departed from. Outputs from one of these gates is selected to the exclusion of the others, to determine which channels shall be used. In cases where uni-directional transmission only is necessary, the same pulse position on both highways may be used and G 3  opened during the whole of each intervening period. Specifications 753,645, 765,681, 822,297, 824,221, 866,653, 904,231 and 904,234 are referred to.

Filed: 1963-06-04
Abstract: 975,489. Drilling. INGERSOLL-RAND CO. June 4, 1963 [June 12, 1962], No. 22237/63 Heading B3C. An air operated drill comprises a body 1 formed by inner and outer cylinders 4 and 2. A piston 5 in the cylinder 4 has a rod 6 attached to an air motor 12 carrying a chuck 13. The reciprocation of the piston 5 effects the feed and return movements of the drill and is controlled by a spool valve 30. With the valve 30 in the position shown in Fig. 1 air is supplied to the chamber 8 to feed the drill forward. This movement is terminated by the contact of an adjusting screw 55 with a reversing valve 38 whereby air is exhausted from a chamber 34 to allow the valve 30 to move to the left, as in Fig. 2, due to a pressure differential. Air is thus exhausted from chamber 8 and admitted to chamber 9 to effect the return movement. The air supply to the rotary motor 12 is controlled by a motor valve 22 which is arranged to open just after the feed motion commences and remains open until the drill has completed the return stroke. This permits the drill to be rotated during both feed and return movements. The rates of these movements are controlled by needle valves 46 and 49. The cycle may be restarted at the end of the return stroke by depressing the recycling valve 41 or momentarily closing the main valve 16 in the feed line 15.

Abstract: 1,214,115. Moulding foodstuffs. UNILEVER Ltd. 20 May, 1969 [24 May, 1968], No. 22311/70. Divided out of 1,214,114. Heading B5A. Apparatus for cutting portions of a foodstuff, particularly those such as fish or meat having a fibrous texture, from a bar comprises a supply channel having a piston therein for movement of a bar of material along said channel, a measuring chamber of the same geometrical cross-section as the bar, located to receive the end of the bar when forced thereinto by the piston, the measuring chamber being arranged to move transversely to the bar to subdivide at least one portion of the foodstuff therefrom. As shown, apparatus for forming and cutting the bar comprises a hopper 1 fixed above a supply channel 3 and separated therefrom by a movable wedge 4 reciprocated by piston and cylinder 7 and 8. A plunger 10 operated by shaft 11 from cylinder 12 forces material in supply channel 3 into cavity 16 which can then be lowered by pneumatic cylinder 15 and the ejecting means 17 actuated to discharge the portion of foodstuff. The wedge 4 is withdrawn and the hopper 1 is filled with foodstuff, e.g. chicken meat, which also fills the supply channel 3. With plunger 10 to the right, the wedge is forced into the position shown, separating the hopper from the supply channel and closing and compressing material therein. The material is compressed by actuating cylinder 12 and foodstuff is forced into the cavity 16 against the ejector 17. The cavity is lowered by cylinder 15, the edge 22 severing the end of the foodstuff portion and closing the supply channel and when the cavity is in the lowered position, ejector 17 is moved by supplying compressed air through cavity 21 and the portion is ejected. The ejection pressure is higher than the pressure of ram 10 and the cavity is raised to its normal position with the ejector 17 held flush with edge 22. When the cavity has reached its normal position, the ejection pressure is reduced and the cavity is again filled. When, after a number of strokes of piston 15, ram 10 approaches the outlet 13 of the channel it is returned to its starting position and wedge 4 is opened to allow more foodstuff to fall into the channel. In alternative embodiment, the cavity 16 may be divided into component cavities by thin vertical members and cutter blades may be provided in the outlet 13 or on the sliding edge 22 to cut the foodstuff before it enters the divided cavity. The cavity 16 may also be formed in an arcuate reciprocating member (Fig. 5, not shown) and a paddle wheel may be provided to assist the transfer of material from the hopper to the supply channel.
